Interestingly, I unplugged the USB hub I had connected (in addition
to the built-in SMSC95xx ethernet) and now it works. It seems that
the USB scanning code is not very happy with either the hub or the
mouse+keyboard I had attached. I'll try to look into this later; for
now I'm happy that I can use the ethernet.
